CONFIRMED


The area in real-life Japan where the games' region lines up is also called Kanto.
Saffron City is located in the same place on this map as Tokyo.
Goldenrod City is located in the same place as Kyoto.
Mount Silver is located where the real-life Mount Fuji is.
Cinnabar Island is located on the island of Izu Oshima. If you recall, Cinnabar Island is destroyed by a volcanic eruption between the first and second generations. Izu Oshima is home to Mount Mihara, which is a volcano.
Vermillion City is located where the real-life city of Yokohama stands.
Cianwood City is the only city whose corresponding real-life city is not considered part of Honshu, but rather of Shikoku. It corresponds with the city of Tokushima.

Hoenn is actually turned sideways to fit onto that map. It's on the island of Kyushu.
The city of Slateport corresponds with the real-life location of Nagasaki.
Mossdeep City is located on the real-life island of Tanegashima. Just like Mossdeep City is home to the Space Center, so Tanegashima is home to Tanegashima Space Center.
Sootopolis City is located on the real-life island of Yakushima. Yakushima's biggest mountain is Miyanoura-dake, which may or may not be volcanic. I'll let you know when I find out.
Evergrande City is located on the real-life island of Amami Oshima, where (I'm not making this up), a species of deadly poisonous snake lives and mongooses are trained to kill them. Sound familiar?

Sinnoh in reality is the island of Hokkaido, which is Japan's largest prefecture. The capital of Hokkaido is Sapporo, which is located in roughly the same location on that map as Jubilife City.
The port city of Otaru in Hokkaido corresponds with the location of Canalave City. The islands where one can catch Darkrai and Cresselia correspond with the locations of Teuri Island and Yagishiri Island.
The Pokemon League is located on the island of Kunashiri. Unlike that spot in the game, this island is volcanic.
Mount Asahi is in the same location on that map as Mount Coronet.

I think we all should know that Unova is based on New York City.
